Application filed March 8, Serial No. 153,258,

To all 'wlwmit may concern:

Be it known that 1, CHARLES J. B. BonansoN, a. citizen of the United States, and a resident of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful'Lubricating Attachment for Metal-Working Machines, of which the following is a specification. r This invention has for its obJect a lubricator for metal working machines as screw machines, and the like in which the tools work in oil, which lubricator is particularly simple construction and highly efiici'ent and durable in use; and the invention consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to, the accompanying drawings in'whi'chl like characters designate corresponding parts in all the views.

Figure 1 is an elevation, partly in section, of one embodiment of my lubricator.

other embodiment thereotl Fig. 3 is a detail view of the detached feed 1 e. P I igs, 4 and 5. are transverse sectional views through one of the nozzles and the feed pipe, the nozzles being shown. in different positions in said figures.

This lubricaton forv metal Working machines comprises generally, a feed pipe, and a plurality of nozzles. associated with the feed pipe, the feed pipe and. each individual nozzle having coacting means for opening and ClOSlI-lg; communication through said nozzle independently of the other nozzles.

1 designates the feed pipe Wl'llCh is here shown as carried by a support, such as a coupling 2, through which the lubricating oil is fed to the pipe 1,,thesupport 2, threading on a suitable feed pipe not shown. 7

3 designates a series or a plurality of nozzles mounted ongthe feed pipe andlas here shown, the nozzles are provided with hubs t sleeved onthe pipe, the hubsabutting Fig. 2 isa View similar to Fig. 1 of anone age-inst the other, eachnozzle having a passage 5 designed toregister with an outlet passageor opening fl; inthe-feed pipe 1. As here shown, the feed pipe is formed with aplnnality on outlets along one side as the 7 lower side thereof, one for each nozzle 3,-

instead of one continuous outlet slot, and the nozzles are movable about the axis of the pipe to carry the passages 5 into and out of P p 1;. r I Thehu'bs of the nozzles are interposed be tween spaced apart abutments on the-pipe 1;, and as here shown one of these abutments is the end face of the hub 7 of-thecou 2, and the other abutment is a disk ors oulder 8' secured to the end ofr'the pipe by means of; a screw 9. V V The hnb's 4e are s'l id'ably mounted on-the feed'pipe 1,.andf means as a spring 10 is employed to press the nozzles along'the pipetoward the abutment 7, this spring being registration with the outlets 6 of the feed interposed between thegdisk 8 and the hubls V of the opposing nozzle 3. Thefeed pipe is adj'ustably mounted in the coupling '2' in order that it may be turned tofch'an'ge the position of the outlet opening shown saidpipe' is'held in its adjusted position by means of a screw 11 threading'in the hub 701" the coupling and having a reduced end 12 which enters one of a series of" holes 13 in the pipe. These holes 13' are partof a series of holes through which the. oil passes from the coupling into the feed pipe; Also by reason of the screw 11, the coupllng 2 can be arranged at an angle in order to, beinost conveniently connected to the source of sup 1y. i

suall y the, feed pipe isarranged with its 6 and as here outlets 5 alongthe lower side thereof butin some instances, it may be desirable ,to slightly rotate the pipe so that the openings are on the front or other side thereof;

In any position of the pipe" upon rotation of a nozzle 8, communication can be cut off or established" through said nozzle;

In Fig. 1, thecouplin'g '2'is show-naslos and spring 10, at each end of the feed" pipe,

: cated midway betweenthe endsofthefeed In Fig. 1, the end nozzles are. shown as in operative position while the other nozzles are shown as turned upwardly so thatno oil can pass therethrough.

' One of the nozzles at the right hand side of the nozz1e2 extension v v r v.

,In Fig. 2', the coupling15 isshown'as mounted on one end of the teed pipe an is shown as formed with an as secured thereto by a screw 17 threading through the hub of the end of the pipe said pipe. I

the coupling and into o'r'a plug in the end of j In Fig. 2 a sleeve 18 is interposed between the coupling and the hub of the near-,

est nozzle, this sleeve 18 serving as an abutment toward which the spring 16 presses the nozzles.

In use, in metal working machines in which the work or cutting is done in lubricating oil some classes of work do not require as many tools as others, and hence it is not necessary to use as many nozzles. By my invention, the oil through the unnecessary nozzles is readily turned off by merely turning up the nozzles so that the passages 5 thereof are out of registration with the outlet openings 6 of the feed pipe.

lVhat I claim is:

l. A lubrieator for metal working machines comprising a feed pipe having an elongated circumfercntially ext-ending slot, a nozzle mounted on the feed pipe and having a discharge opening of smaller diameter than the length of'the slot and movable about the pipe to diflerent radial angles thereto with its discharge opening in full registration with the slot at different angles of said nozzle and being movable completely out of registration with the slot to close the slot, substantially as and for the purpose described.

2. A lubricator for metal working machines comprising a feed pipe, nozzles mounted on the feed pipe and having a discharge opening, the nozzle being movable about the pipe and having a discharge opening arranged to receive the full amount of lubricant therefrom when arranged at various angles relatively to the pipe and being additionally movable relatively to the pipe to cut off the communication between the pipe and the nozzle substantially as and for the purpose specified.

3; A lubricator for metal working machines comprising a feed pipe and a plurality of nozzles mounted on the feedv pipe and rotatable about the same independently of each other, the feed pipe having openings discharging into the nozzles and the nozzles having discharge openings 2 rranged to come in full registration with the openings of the pipe at various angles of the nozzles and to close said openings in the pipe upon additional rotation, substantially as and for the purpose described,

i. A lubrica-tor for metal working Ina-- chines comprising a feed'pipe, a plurality of nozzles rotatably andslidably mounted on the feed pipe, the feed pipe and the nozzles having openings, each nozzle being rotatable about the feed pipe for carrying its opening into and out of registration with the opening of the feed pipe, an abutment for the nozzles, and means tending to press the noz zles toward the abutment, substantially as and for the purpose set forth. 7

5. A lubricator for metal working machines comprising a feed pipe, a plurality of nozzles rotatably and slidably mounted on the feed pipe, the feed pipe and the nozzles having openings, each nozzle being rotatable about the feed pipe for carrying its opening into and out of registration with the opening of the feed pipe,an abutment for the nozzles, and a spring acting on one of the end nozzles and tending to slide the nozzles toward the abutment, substantially as and for the purpose described.

6. A lubricator for metal working ma.- chines comprising afeed pipe having a pair of spaced apart abutments thereon, a plurality of nozzles rotatably and slidably mounted on the feed pipe between the abutments, the feed pipe and each nozzle having openings and each nozzle being movable about the feed pipe to carry its opening into I and out of registration with the opening of the feed pipe, and a spring between the one of said abutments and the contiguous nozzle, substantially as and for the purpose specified.

7. A lubricator for metal working machines comprising a feed pipe, a support therefor, a plurality of nozzles associated with the pipe, the pipe being rotatably mounted in its support to change the direction of the nozzles when the nozzles are in their operative position, and means for holding the feed pipe in its adjusted position, substantially as and for the purpose set forth.

8. A lubricator for .metal working machines comprising a feed pipe, a support for the feed pipe, the feed pipe having its outlets along one side thereof, nozzles mounted on the pipe and adjustable about the same, each nozzle being movable independently of the others about the pipe to carry its opening into and out of registration with an outlet of the feed pipe, the feed pipe being rotatably mounted in its support to change the position of the outlets thereof, and means for holding the pipe in its adjusted position, substantially as and for the purpose described.
